On Order-Preserving and Verbal Embeddings of the Group $\mathbb{Q}$

Abstract

We show that there is an order-preserving embedding of the additive group of rational numbers $\mathbb{Q}$ into a 2-generator group $G$. The group $G$ can be chosen to be a solvable group $G$ of length 3, which is a minimal result in the sense that it cannot be chosen to be neither solvable of length 2, nor a nilpotent group. For any non-trivial word set $V\subseteq F_{\infty }$ there is an order-preserving verbal embedding of $\mathbb{Q}$ into a 2-generator group $G$. The embeddings constructed are subnormal.
